We use advanced conversion technology to preserve fonts, formatting, tables, and page layout. Complex documents with unusual fonts or embedded objects may have minor differences, but content accuracy is always maintained.
Yes. Our OCR (Optical Character Recognition) technology extracts searchable text from scanned PDFs. Pro users get access to enhanced OCR for better accuracy on complex documents.
For PDF output, fonts are embedded to ensure your document looks the same everywhere. For other formats, we use the closest available system fonts to match the original styling.
All uploads use 256-bit SSL encryption. Files are automatically deleted within 2 hours. We never access, store, or share your document contents. GDPR compliant.
Password-protected files must be unlocked before conversion. Remove the password first, then upload for conversion. We cannot bypass document encryption.
